CHESS

Scotch Game

Raymond Keene

The World Championship resumed at the Palais des Congres in Lyon last Satur- day with Karpov taking the advantage of the white pieces for the 13th game. For the second time in the match Kasparov re- sorted to his old flame the Grunfeld Defence and after a sharp opening tussle, during the course of which both players felt the need to sacrifice a rook for a menacing opposing knight, the game burnt out to a drawn rook and bishop ending. Kasparov tried to flog a dead horse until the adjourn- ment in his efforts to extract something but after the sealed move 42 Kxd3 Rxa4 42 d6 Black has to play 43 . . . Ral (threatening

. . Rdl +) when a draw by repetition occurs on 44 Kd2 Ra2+ 45 Kc3 Ral 46 Kc2 Ra2+ 47 Kd3 since White can never allow Black's rook to reach the 'd' file behind his own passed pawn.

Kasparov — Karpov: World Championship Fin- al; Game 14, Scotch Game.

1 e4 e5 2 Nf3 Nc6 3 d4 This is the first time Kasparov has played the Scotch Game in this match; indeed, it may be the first time he has ever played the Scotch Game. The Scotch has only occurred twice in world championship matches, Steinitz-Zukertort, 1886, where Black played 3 . . . ed4 4 Nd4 Bc5 and Steinitz- Chigorin, 1892, when Black played 4 . . . Qh4. 3 . . . exd4 4 Nxd4 Nf6 5 Nxc6 bxc6 6 e5 Qe7 7 Qe2 Nd5 8 c4 Ba6 9 b3 9 Qe4 Nb6 10 Nd2 0-0-0 11 c5 Bxfl 12 cxb6 Ba6 13 bxa7 was Timman-Karpov, London 1984. It is interesting that the a7 pawn seems to be Black's main weakness in this line, but because it is so far from the scene of the action it is often unimportant. 9 . . . 0-0-0 10 g3 Re8 11 Bb2 f612 Bg2 fxe5 13 0-0 h5 This all looks like Kasparov preparation since he had now used eight minutes to Karpov's 65. 14 Qd2 Nf6 15 Qa5 This wins back the pawn while simul- taneously the white queen crashes through to attack the black king. Once the queen is on a7 White can consider various ponderous attacking plans such as a4 – a5 – a6 or Na3 – c2 – b4 – a6. However, both of these are very slow and White has to reckon in the meantime with a backlash against his own king. 15 . . . Bb7 16 Ba3 Qe6 17 BxfB Rhxt 18 Qxa7 Qg4 An excellent counter- attacking move after which Kasparov thought for 53 minutes, a record for one move in this match, equal with Karpov's (game 4). 19 Na3 h4 20 Nc2 h3 21 Bhl Ne4 n a4 If 22 f3 Nxg3 23 Rf2 (23 fxg4 Ne2 mate) 23 . . Qg6 24 hxg3 Qxg3+ 25 Kfl c5 26 QxcS Bxf3 27 Bxf3 Rxf3 28 Rxf3 (42+ 29 Kel Qxf3 with sufficient compensa- tion. Kasparov prefers to wrench the attack into his own hands with a sacrifice of the exchange. 22 . • . Nc3 23 Rael Ne2+ 24 Rxe2 Qxe2 25 NM

(Diagram) 25 . . . d5 The times taken were now 107 minutes for White and 135 for Black. Since each player has 150 minutes to escape to the time control at move 40 one can appreciate how seriously short of time Karpov was. It is all the more praiseworthy then that he plays for a win rather than going for 25 . . Rf3 26 Na6 Kd8 27 Qb8+ Ke7 28 Qxb7 Rxf2 29 0b4+ d6 30 Rf2 Qdl+ with a forced draw by perpetual check. 26 cxd5 cxd5 27 Bxd5 If instead 27 Nxd5 Qa6 28 0c5 Qd6 beats off the attack. 27 . . .

Qd3. The text assures him of a draw at worst and also rescues Karpov from his clock trouble. 36 fxe3 Qxe3+ 37 Khl Qe4+ 38 Kgl Qe3+ 39 Khl Qe4+ 40 Kgl Rd8 41 Qc2 Draw agreed. Kasparov sealed his 41st move. A superb duel in the same class as games 3 and 4 from New York.

As I write, England are sharing first place in the chess Olympics in Novi Sad in Yugoslavia and our team of Nigel Short, Jon Speelman, John Nunn, Michael Adams, Murray Chandler and Julian Hodgson has an excellent chance of car- rying off the gold medals for the very first time. The Hungarian women's team, which consists almost entirely of three Polgar sisters, is leading the female section, but they had a nasty fright in their match against the USSR where the veteran Gap- rindashvili destroyed the prodigy Judit.
